In Fig. 8, perforations 25 and 2'6 are formed in the skirt 23A and the flexible element is passed through both of them, as shown at f. It is so obvious that the flexible element may be passed through a single perforation, such as 25, and its end knotted, that illustration of this simple modication is not necessary. Such an expedient is illustrated in Fig. 9 which will now be described.

tected. A liner 20B is placed over this surface. Surrounding it is a shell 19B having a channel HB and an orice l2B. The liner is perforated, as at 2`1. 'I'he end of the flexible element B is shown as passed through this perforation and knotted, as at y.

This device is applied to the member D by winding the flexible element into the channel HB by relative rotation between the member D and the I 0B. The liner will be pressed against or into the ornamental surface e.

Several modifications of this invention have been shown and described. Others may be made without departing from its spirit and scope and I intend no limitations other than those imposed by the appended claims.

What I claim is:

1. The combination of a protector comprising a rigid cylindrical shell adapted to be placedadjacent acylin-drical surface of a member to be protected and a flange at one end of said shell, and a cup-shaped liner closed at one end, a flange at the other end and an intermediate cylindrical portion, the flange of the liner being adapted to be engaged by the ange of the protector to hold the liner in place.

2. The combination of a protector comprising a rigid cylindrical shell adapted to be placed adjacent a cylindrical surface of a member to be protected and a ilange at one end of said shell, la cup-shaped liner closed at one end, a flange at the other end, an intermediate cylindrical portion, and a skirt concentrically spaced from said intermediate portion and connecte-d therewith by the flange, the flange of the liner being adapted to be engaged by the ange of the protector to hold the liner in place.

3. The combination of a protector comprising a rigid cylindrical shell adapted to be placed adjacent a cylindrical surface of a member to be protected land a flange at one end of said shell, a cup-shapedliner closed at one end, a flange at the other end, an intermediate cylindrical portion, and a skirt concentrically spaced from said of a protected member, the flange of the liner being adapted to be engaged by the ilange of the protector to hold the liner in place.

4. The combination of a protector comprising a rigid cylindrical shell adapted to be placed adjacent a cylindrical surface of a member to be protected and a ange at one end of said shell, a cup-shaped liner closed at one end, a flange at'the the flange, said skirt extending through the shell of the protector and being arranged to be interposed between said shell and an adjacent surface protector to hold the liner in place.

5. The combination with a rigid cylindrical shell adapted to be cal surface of a member, a exible element ar around a part thereof.

6. The combination with a rigid cylindrical shell adapted to be placed adjacent a cylindrical surface to the member by being wound between the shell with the member, and a liner interposed between the shell and the member, said liner being arranged to hold an end of the vflexible element in non-rotative relation with the member.
